I have a 2 yr old 25cc Craftsman POS weed eater. It starts on one pull and runs perfect for about 3 minutes, then boggs out. I have replaced fuel lines and filters, replaced the gas with a perfect mix, cleaned air filter, and stripped down and cleaned the carb fully. I am real close dumping it and buying an electric one. I saw several similar posts - is Craftsman just junk nowadays? Any ideas to salvage it?

How about the spark plug? Anyway, does Craftsman warranty their tools like that?

Sounds like it needs a new diaphram and gaskets installed in the carb and the carb mixture screws set
But craftsman weedeaters are made by the cheapest bidder.
